Question
An engineer has designed an anchor redundancy for guest clients connecting to SSID with auto- anchor configured. After adding a second Anchor WLC under the SSID mobility anchor list, clients are load- balanced between existing and new anchors instead of having one anchor as active and the other one as standby. Which feature should be included in the design that will be configured on the WLC running 8.1 or above to ensure anchor redundancy?
Options
- AAuto-Anchor Foreign Mapping
- BAP groups
- CGuest Anchor Priority

Explanation
When multiple Anchor WLCs are configured in the mobility anchor list, the default behavior on Cisco WLCs is to load-balance client connections across all anchors. To achieve true active/standby redundancy (where one anchor handles all traffic and the other only takes over on failure), you must configure Guest Anchor Priority, introduced in WLC software version 8.1. This feature lets you assign a numeric priority value to each anchor WLC in the list - the anchor with the highest priority becomes the active anchor, and the lower-priority anchor acts as standby. Without this feature, all anchors are treated as equal peers and clients are distributed among them.
